4 Product Description

MIC Series 440 cameras are high-specification, weatherproof, ruggedized, fully functional day/ night PTZ cameras that have been designed to offer a reliable, robust, and high-quality surveillance solution for extreme security applications.

MIC440 models have a 18x or 36x optical zoom (12x digital) and flexible mounting options (upright or inverted) to achieve the perfect field of view.

MIC440 cameras meet the requirements of ATEX Directive 94/9/ EC Exd IIC T6 and CSA Class I, Division 1, Groups CD, Class II, Division 1, Groups EFG, T6 for safe use in explosive atmospheres such as those found in oil, gas, chemical processing sites, and petrochemical refineries.

Precision-engineered to exacting standards, MIC cameras offer numerous benefits over traditional dome and PTZ cameras. Rated to an industry-leading IP68, the compact, vandalresistant, 6 mm thick aluminum camera housing is pre-treated and then painted with polyester powder coat paint (Jet black (RAL 9005) or Signal white (RAL 9003)). Brushless motor technology ensures ultra-reliable, whisper quiet operation with full 360° continuous pan and 320° tilt control. The optically perfect, flat viewing window and integrated wiper ensure that razor-sharp images are captured in even the most demanding conditions.

5 Installation of a MIC440 Camera

This chapter provides an overview for the installation of a MIC440 camera.

Caution!

The MIC440 camera is designed for use with flammable gases and vapors covered by

!apparatus groups IIA, IIB and IIC and with temperature class T6. The product is certified for use within the ambient temperature range of -20 °C to +60 ºC and must not be used outside this range.

While a MIC440 camera is certified for installation in a hazardous area, its power supply unit (PSU) is not. The PSU itself can be installed in either a non-hazardous area or in a hazardous area. If installed in a hazardous area, the PSU must be placed inside a certified enclosure that is certified for use in hazardous areas.

Warning!

!ROUTING OF EXTERNAL WIRING MUST BE DONE THROUGH A PERMANENTLY EARTHED METAL CONDUIT.

5.1 Mounting the Conduit Gland and Cable

The MIC composite cable (8 mm) required to connect the MIC440 to its power supply consists of two pairs (24AWG) plus 4 cores of (22 AWG), 2 cores of (24 AWG), and one coax core for the video signal to a maximum distance of 25 m.

Warning!

!Bosch recommends connecting the cable to the unit before taking the unit for mounting onsite.

To mount the conduit gland and cable, follow these steps:

1.Remove the 4 x M8 Hexagon bolts holding the conduit adapter (DCA) to the MIC440 unit. Remove the DCA.

2.Fit the unterminated ends of the composite cable through the 20 mm threaded gland hole in the DCA. Allow approximately 100 mm of free cable on the inside to connect to the 12way cable connector.

3.Screw the Exd conduit gland into the DCA, maintaining approximately 100 mm of cable on the inside of the DCA to enable the cable connector to be inserted freely into the MIC unit base connector.

4.Connect the 12-way cable connector into the matching connector in the base of the MIC unit.

5.Ensure that the connector is fitted properly in the camera’s integral plug. Turn the socket thread ring approximately two and a half turns to fasten the two halves of the connectors together properly.

6.Bolt the DCA onto the MIC440 unit; tighten the 4 x M8 hexagon bolts.

7.Ensure that there are no trapped cables.

8.Ensure that there is some slack cable in the DCA, then tighten and seal the Exd barrier gland per the instructions included with the gland. The unit with the cable tail is now ready for on-site installation.

PSU Installation and Setup in a Hazardous Area

Caution!

Any junction box or enclosure used for mounting the power supply or separating cable cores MUST BE appropriately rated for the installation. MIC PSU enclosures are not Exd rated and

!must be placed inside a certified enclosure if installed within a hazardous area.

For additional protection in hazardous area installations, suitable metal conduit must be used externally for the composite cable run to connect the power supply to the Exd conduit gland (not supplied) in the Deep Conduit Adapter (MIC-DCA).

Installation of the PSU within a hazardous area must have the standard PSU enclosure placed inside an appropriate certified enclosure and four (4) Exd conduit glands (NOT supplied). The power supply PCB is usually re-housed, by a third party company, within an Exd enclosure which is then factory certified and shipped to site. Follow all manufacturers’ instructions when installing a third party Exd enclosure.

The figure below illustrates a typical installation of both a MIC440 and a MIC PSU in a hazardous area. Note that the PSU is installed inside an enclosure that is certified for use in hazardous areas.
